When I was fourteen, I spent most of my spare time making mixtapes for girls that I would never actually give to them. Robert Nay made a game that's been downloaded over two million times.
For more than a month, Robert spent a couple of hours each day on the game, ultimately writing more than 4,000 lines of computer code, his mother said.
Kari Nay said she helped him design some of the puzzles in the game, but he came up with the concept and did everything else on his own.
According to its App store description "Bubble Ball" is a "fun, new physics puzzle game, where you will test your ingenuity and thinking skills to get the bubble to the goal."
